A speech synthesis engine counts the matches it finds for the specified parameters, and returns the voice when the count equals the voiceAlternate parameter.

Use the GetInstalledVoices() methods and VoiceInfo class to obtain the names and attributes of installed text-to-speech (TTS) voices that you can select.

To stop using the voice specified by StartVoice(VoiceGender, VoiceAge, Int32) call EndVoice().
